Ballistic transport in a disordered, boundary-driven XXZ spin chain. — •Johannes S Hofmann¹, Adam McRoberts², and Roderich Moessner¹ — ¹Max Planck Institute for the Physics of Complex Systems, Nöthnitzer Str. 38, 01187 Dresden, Germany — ²International Centre for Theoretical Physics, Strada Costiera 11, 34151, Trieste, Italy

Recent experiments on Google's sycamore NISQ device on spin transport realised ballistic transport in a edge-driven XXZ chain without disorder; and theoretical works on the classical variant demonstrated the survival of ballistic regime in the easy-plane upon the introduction of bond disorder. Here, we consider various generalisations of this set-up.
